3-Aminopropyltriethoxysilane
3-Aminopropyltriethoxysilane (APTES) is a versatile silane coupling agent used to functionalize silicon-based surfaces like Si3N4 for biomolecule immobilization. It serves as a flexible spacer, enhancing the activity and accessibility of attached probes in biosensing platforms. This application is fundamental for in vitro diagnostic assays, surface plasmon resonance (SPR) studies, and the development of microarray and lab-on-a-chip devices.
